Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. These carbohydrates store energy. Oxygen (O2) is a byproduct that is released into the atmosphere. This process is known as photosynthesis.
Oxygen is needed for respiration, and carbon dioxide is emitted in the process. This inhaled oxygen is needed to produce energy (ATP) inside living cells from the process known as cellular respiration. On the other hand, carbon dioxide is utilized by plants for photosynthesis to produce carbohydrates.
